Iran executed two men in separate cases Wednesday, accusing one of spying for Israel and another of being a member of the Islamic State group, state media reported.

A report by the judiciary news website Mizanonline identified the alleged spy as Rouzbeh Vadi, who was accused of relaying classified information to Israel�s intelligence service, the Mossad.

Authorities said Vadi provided information about an Iranian nuclear scientist who was killed during Israel�s June airstrikes on Iran, according to the report, which did not identify the scientist or the time and place of Vadi�s arrest.

Vadi met the Mossad officers five times in Vienna, Austria, the report said.

Israel�s ambassador to France, Joshua Zarka, said in June that Israel�s 12-day war on Iran included targeted strikes that killed at least 14 physicists and engineers involved with Iran�s nuclear program.

Iran has hanged seven people for espionage during the conflict with Israel, sparking fears from activists that the government could conduct a wave of executions.

Iran separately hanged a member of the Islamic State group on Wednesday after he was convicted of plotting sabotage, Mizanonline reported.

Officials accused Mehdi Asgharzadeh of being a member of the Islamic State group who participated in military training in Syria and Iraq before illegally entering Iran with a four-member team who were killed in a fight with Iranian security, the news site reported.

Authorities said Iran�s Supreme Court upheld the sentences of lower courts and followed full legal procedures before executing both men, Mizanonline reported.
